i3c: add addr and lvr to i2c_dev_desc structure
I need to store address and lvr value for I2C devices without static definition in DT. This allows secondary master to transmit DEFSLVS command properly. Main changes between v4 and v5: - Change in defslvs to use addr and lvr from i2c_dev_desc structure - Change in CDNS and DW drivers to use addr and lvr from i2c_dev_desc structure Signed-off-by: Przemyslaw Gaj <pgaj@cadence.com> Signed-off-by: Boris Brezillon <boris.brezillon@collabora.com>
